WASHINGTON (CBSDC/AP) — A notorious hacking group claims on Twitter that it hacked Facebook which caused outages and slowdowns on the social media website for a few hours Thursday night.

Anonymous tweeted Thursday night that it looks “like Facebook is having packet problems.”

The group later added, “Oh yeah … RIP Facebook a new sound of Tango down (expletive).”

Facebook has yet to comment.

The reported hacking comes as Facebook’s stock regains some of its losses from the past few days.

The stock jumped $1.41, or 5 percent, to close Thursday at $29.60. That comes after three consecutive days of declines. The stock is still down 22 percent since its highly anticipated initial public offering two weeks ago.

Facebook Inc. began trading on the Nasdaq Stock Market on May 18. The day started with a delay due to trading market glitches and didn’t get much better from there.

The company, along with the investment banks that led the IPO, is also the subject of at least two shareholder lawsuits. They allege that analysts at the large underwriting investment banks cut their financial forecasts forFacebook just before the IPO and told only a handful of clients. Morgan Stanley has declined to comment.Facebook calls the lawsuits “without merit.”

Standard & Poor’s equity analyst Scott Kessler, who has a “Sell” rating on Facebook’s stock, lowered his target price to $27 from $30 on Thursday. He also lowered his earnings forecast to 39 cents from 40 cents for 2012.
